  <div>
   <div class="section">
    <h4 class="sectiontitle">现象描述</h4>
    <p>MRS平台安装Graphbase服务后会在Hbase应用的default命名空间下创建元数据表meta_graph和graphbaseORM_systemNotifications，执行恢复的目标集群如果没有安装Graphbase服务，将恢复失败。</p>
   </div>
   <div class="section">
    <h4 class="sectiontitle">可能原因</h4>
    <p>Graphbase服务的元数据表meta_graph和graphbaseORM_systemNotifications恢复时，需要使用Graphbase服务校验表信息。由于恢复的目标集群未安装Graphbase服务，会导致校验表信息失败，恢复任务失败。</p>
